`xxhash-addon` is a high-performance Node.js addon that provides native bindings to the xxHash hashing algorithm, offering speeds up to 50 times faster than Node.js's built-in crypto MD5. It supports multiple xxHash variants (XXH32, XXH64, XXH3 64-bit, and XXH3 128-bit) and is designed for developers who need fast, reliable hashing in their applications, particularly those working with large datasets or performance-critical systems.
